l Application filed July 5, 1900. Serial No. 22,496. (No model.)

To all whom it may concern:

Be it known that I, AUGUST KRAsTIN, a citi- `zen of the United States,residing at No. 50

Portland street, Cleveland, in the county of Cuyahoga and Slate of Ohio,have invented for; and the object of my improvement is to i rendertheconnection of the Wheel-hub with the axle absolutely safe and trueand con- I attain these objects in the manner and by the means asillustrated in the accompanying drawings, in

i Whiching part of the compensating gearing.

shown in reduced scale.

Like letters of reference denote like parts in the drawings andspecification.

The characteristic feature of my invention consists in the equipment ofthe axles, their casing, and the Wheel-hubs of the hind running-gear ofand for a motor-vehicle. The axleA is used in duplicates, which areconnected by means of a compensating gear and running within a suitablecasing B. (See Figs. l and 1i.)

. The casing B is equipped With rings d d for the reception of balls bb, upon which the axles rotate. The casing also is used in duplicates,which are joined over the compensating gearing, as seen in Fig. 4. At ca bracket is formed for the reception of the springs. The outer part ofthe casing terminates in a cup d, within which is fitted the ring d,above mentioned, also the packingring e. (See Fig.'l.) To the innerterminal of the axles is secured a bevel-Wheel f, form- At g a thread isformed for the reception of the collar C, of which the cone part 7i,forms a race for the balls b. Furthermore, said collar enables accurateadjustment of the axle with respect to the casing, and all lost motionof the axle can thereby be eliminated,

and the balls themselves are confined between parts which formadjustable raceways. At h another cone is formed, against which the hubD of the wheel is brought to bear. Around the circumference of saidcollar and between the cone-faces are formed a series of lugs vl,between which engage a series of lugs j, which project from the innercone or ring part K of the hub. (See Figs. l and 2.) The hub itself isgrooved in its bore, as at Z, which groove engages over a feather 'mupon the axle. The outer part of the hub is countersunk, as at n, With abeveled shoulder, as at n. Within said counterpart is fitted the nut E,Which screws over the outer terminal O of the axle. Onto the flangesppthe spokes are fastened in ihe usual manner. Owing to the cone-faces hand n', a concentric gripping action can be edected upon the hub, `whichresults in a true running of the wheel. The engagement of the hub Withthe collar forms a secure lock for the latter. Thus when once adjustednone of the parts can or Will become.

loose. Furthermore, by means of the packing e dust and dirt areprevented from entering the ball-chamber. Therefore the balls areexposed and subjected only to natural wear and tear, and even this isreduced to a minimum owing to the accurate adjustment in this improvedhub-and-axle construction.

What l claim, and desire to secure byLetters Patent, is-

1. In combination, an axle, a wheel-hub, a

casing for said axle, a race-ring in the cup terminal 0f said casing,balls, a double conefaced notched collar, and a cone-faced nut, thelatter two elements having screw connection upon and with said axle foradjustment of same and reception of the Wheel-hub, which has a featherconnection with the axle, there being counterpart cone-faces for saidcollar and nut and an interlocking engagement with said collar allconstructed and arranged substantially as and for the purpose set forth.

2. The combination of an axle, an adjustable doublefaced cone -collarhaving lugs which project between said cone faces, a feather and acone-faced nut, a wheel-hub fitting over said feathered axle, engagingsaid collar and held secure by said nut, a casing for the axleterminating in a cup, a ring IOO in said cup and balls for said axle allconsaid nut all constructed and arranged substructed and arrangedsubstantially as and stantally as and for the purpose set forth. for thepurpose set forth. In testimony whereof I hereunto affix my 3. Thecombination of av revoluble axle signature in presence of two Witnesses.equipped with a notched collar a feather and AUGUST KRASTIN. a nut, anda Wheel-hub adapted to fit said axle and equipped with lugs whichinterlock with said notched collar and are secured by Witnesses:
